Problems solved by technology

For example, when the vehicle is driving, the occupants of the vehicle wake up the equipment in the vehicle by voice, but the vehicle is affected by tire noise, wind noise, engine noise, air conditioning noise, music in the car, and speaker interference in the car. The accuracy of vehicle sound zone detection is greatly reduced

Abstract

The embodiment of the invention discloses a sound source position determination method and device, a readable storage medium and electronic equipment, and the method comprises the steps: carrying outthe modeling of respective transfer functions based on a plurality of positions in a set space, and obtaining transfer function matrixes corresponding to the plurality of positions in the set space; collecting a sound signal emitted by at least one position in the plurality of positions; and processing the sound signal by adopting a maximum likelihood method in combination with the transfer function matrix, and determining the position of a sound source emitting the sound signal in the plurality of positions. According to the embodiment of the invention, the maximum likelihood method is adopted to carry out the sound area detection, so that the influence of the offline modeling amplitude error on the sound area detection result can be avoided; and the ideal transfer function in the maximumlikelihood function is replaced by the modeling transfer function, so that the detection accuracy of the sound zone is improved.

Description

technical field [0001] The present disclosure relates to a sound source localization technology, in particular to a method and device for determining a sound source position, a readable storage medium, and an electronic device. Background technique [0002] With the development of voice recognition technology, voice recognition has been applied to various fields, for example, technologies such as voice control and voice wake-up. In the application of voice wake-up, in order to facilitate multiple users to control the target, it is necessary to determine the location of the wake-up person when waking up. For example, when the vehicle is driving, the occupants of the vehicle wake up the equipment in the vehicle by voice, but the vehicle is affected by tire noise, wind noise, engine noise, air conditioning noise, music in the car, and speaker interference in the car. The accuracy of vehicle sound zone detection is greatly reduced. Contents of the invention [0003] In order...
